That is not why this is shocking. This proceeding is shocking because the legal basis for this change is dependent on a false statements about the technology involved. It goes beyond just, "Republicans prefer deregulation," or, "Republicans favor market-based approaches." There is plenty of room and a general need for debates about what policy approaches are best, but there is no room for debate about the answer to technical questions.
Engineers and researchers submitted hundreds of comments to the FCC trying to correct the falsehoods presented in the NPRM. The FCC did not simply ignore those comments. The draft rules specifically cite those comments and totally dismiss them as "not persuasive." Only commentary from ISPs was "persuasive" in this proceeding, and the ISPs omitted facts that were inconvenient for them (the point of public commentary is in part to fill in the omissions that lobbyists would obviously make).
Sorry, but I do not buy the "what do you expect from Republicans" argument. I expect Republicans to be pro-markets, even pro-big-business; I expect Republicans to favor deregulation. It is not acceptable to pursue that agenda by ignoring expert answers to technical questions, regardless of party affiliation. It is one thing to interpret facts -- for example, the draft rules interpret the fact that edge services can be accessed via ISP networks as ISPs providing a capability to their customers, which is bizarre but within the bounds as far as policy debates go. To simply dismiss facts that are being presented to you by experts, when you have a legal obligation to receive and consider such facts, is another matter entirely.
Yes, I expect the party of deregulation to base its policy goals on facts, as interpreted through the lens of a pro-business/pro-markets approach, and not some convenient fantasy.
